Two sets of nitrate (NO3-) concentration data, obtained from Central Greenland and East Antarctic (Dronning Maud Land) ice cores, were analyzed statistically. Distinct century-scale (50-150 yr) variability was revealed in both data sets during AD 1576-1990. It was found that century-type variation in Greenland and Antarctic nitrate correlates fairly significantly with the corresponding Gleissberg cycle: (a) in sunspot number over 1700-1970 AD; (b) in Be-10 concentration in Central and South Greenland over 1576-1970 AD. Thus, presence of century-scale relationship between polar nitrate and solar activity was confirmed over the last 4 centuries. That proves that NO3- concentration in polar ice caps could serve as indicator of long-term solar variability. (C) 2014 Elsevier Ltd. All rights reserved.
